Frightful Presence (Ex)

Source: Advanced Player's Guide, p. 63

An eidolon becomes unsettling to its foes, gaining the frightful presence ability. The eidolon can activate this ability as part of an offensive action, such as a charge or attack. Opponents within 30 feet of the eidolon must make a Will save or become shaken for 3d6 rounds. The DC of this save is equal to 10 + 1/2 the eidolon’s HD + the eidolon’s Charisma modifier. If the eidolon has at least 4 more Hit Dice than an opponent, that opponent becomes frightened instead. Foes with more HD than the eidolon are immune to this effect. The summoner must be at least 11th level before selecting this evolution.
